Reboot loses monitor settings

Asked by Roger Smith on 2018-07-05

A Long time Linux / KDE user and new user of KDE Neon, using 5.13, and so far am very happy with it.
Except:
I have a desktop with dual monitors, identical monitors except one has HDMI and the other doesn't. AMD graphics card using the Radeon driver.

I set the monitors the way I want them, left and right and nominate the DVI connected monitor as Primary as it is on the left.

Every single time I boot the monitor settings have swapped the two monitors over, so the main monitor is the HDMI monitor on the right.

Also the ( I presume) first run monitor set up app pops up on the screen every time. Which I ignore and close (I did try it once and it turned my screen into gibberish) and return to display and monitor in settings to change them back to the way I want them. These settings simply do not retain the settings I set when I reboot.

Any ideas how I can make the setting a little more permanent. Recently came from Mint 18.3 (bailed with no KDE in 19) and previously a long time user of openSUSE and have never had this issue before, with the same desktop and monitors.
